Fake Googlebot Checker
Verify if a bot claiming to be Googlebot is actually from Google by checking its IP address against Google's official IP ranges.
What this tool does
Bots frequently disguise themselves as Googlebot by setting their user agent string to match Google's crawler. This is trivial to fake and extremely common. Scrapers, spammers, and vulnerability scanners use this technique to bypass robots.txt rules and WAF protections that whitelist Googlebot.
The only reliable way to verify a Googlebot claim is to check whether the request came from an IP address that actually belongs to Google. Google publishes its official crawler IP ranges, and this tool checks any IP address against those ranges instantly.
- Verify any IP address against Google's official crawler IP ranges, updated regularly
- Instant results showing whether the IP is a verified Google IP or an impersonator
- Detailed verification data including the matching IP range, data centre location, and network owner
- Understand bot impersonation and why it matters for your site's security and SEO
How it works
Enter an IP
Paste an IP address from your server logs that claims to be Googlebot.
Check ranges
The IP is checked against Google's published crawler IP ranges.
Get verification
See whether the IP is a verified Google crawler or a fake.
Example results

- Verdict
- Not a Google IP — bot impersonation
Why bot verification matters
SEO protection
Fake Googlebots ignore robots.txt and crawl-delay directives. They waste your crawl budget and can cause search engines to see duplicate content issues.
Security
Attackers impersonate Googlebot to bypass WAF rules and rate limits. Vulnerability scanners and scrapers use this to fly under the radar.
Accurate analytics
If fake Googlebots are counted as real search engine traffic, your bot analytics are skewed. Verification gives you accurate crawler data.
Bandwidth savings
Fake crawlers consume server resources and bandwidth. Identifying and blocking them reduces load and hosting costs.
How bots impersonate Googlebot
Bot impersonation is trivially easy. Any HTTP client can set its user agent string to Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) and most servers will treat it as the real Googlebot. This is why user agent strings alone are never sufficient for bot identification.
The reliable method is reverse DNS verification or IP range checking. Google publishes its official crawler IP ranges in a JSON file. By checking whether a request's source IP falls within these ranges, you can definitively verify whether a claimed Googlebot is genuine.
Beyond Googlebot
Googlebot is the most commonly impersonated crawler, but the same technique applies to other bots. Bingbot, GPTBot, and other crawlers all have official IP ranges that can be verified. If you need to verify multiple bot types across all your traffic, a dedicated solution is more practical than manual IP checks.
Automatic bot verification on all traffic
This free tool checks one IP at a time. LogLens automatically verifies every bot across all your traffic in real-time, flagging fakes and impersonators as they appear.
